Katharina Irrgang 1882278b5b 🎨 configurable logging with bunyan (#7431)
- 🛠  add bunyan and prettyjson, remove morgan

-   add logging module
  - GhostLogger class that handles setup of bunyan
  - PrettyStream for stdout

-   config for logging
  - @TODO: testing level fatal?

-   log each request via GhostLogger (express middleware)
  - @TODO: add errors to output

- 🔥  remove errors.updateActiveTheme
  - we can read the value from config

- 🔥  remove 15 helper functions in core/server/errors/index.js
  - all these functions get replaced by modules:
    1. logging
    2. error middleware handling for html/json
    3. error creation (which will be part of PR #7477)

-   add express error handler for html/json
  - one true error handler for express responses
  - contains still some TODO's, but they are not high priority for first implementation/integration
  - this middleware only takes responsibility of either rendering html responses or return json error responses

- 🎨  use new express error handler in middleware/index
  - 404 and 500 handling

- 🎨  return error instead of error message in permissions/index.js
  - the rule for error handling should be: if you call a unit, this unit should return a custom Ghost error

- 🎨  wrap serve static module
  - rule: if you call a module/unit, you should always wrap this error
  - it's always the same rule
  - so the caller never has to worry about what comes back
  - it's always a clear error instance
  - in this case: we return our notfounderror if serve static does not find the resource
  - this avoid having checks everywhere

- 🎨  replace usages of errors/index.js functions and adapt tests
  - use logging.error, logging.warn
  - make tests green
  - remove some usages of logging and throwing api errors -> because when a request is involved, logging happens automatically

- 🐛  return errorDetails to Ghost-Admin
  - errorDetails is used for Theme error handling

- 🎨  use 500er error for theme is missing error in theme-handler

- 🎨  extend file rotation to 1w
